[0029] Working principle: When in use, the top of the support arm 1 is stuck on the channel steel of the belt conveyor frame, and then the locking bolt 13 is tightened. The top of the support arm 1 bends to a certain extent to fix the support arm 1 on the belt conveyor. The lower pallet 12 supports the idler. Remove the old lifting lug fixing bolt 13 to remove the old lifting lug. Align the new lifting lug slot 27 with the idler shaft and snap it in upwards, then install the bolt 13 back to complete the replacement of the lower lifting lug. With the above settings, the idler can be lifted without disassembling the idler, saving time and effort during replacement and facilitating the replacement of the lower lifting lug by the staff. The support 25 is inserted into the clamping seat 26 to connect the lower arm 22 with the screw rod 23. Then, the staff can rotate the screw rod 23 according to requirements to adjust the lengths of the upper arm 21 and the lower arm 22, and then adjust the height of the pallet 12, so as to conveniently adjust the lifting height of the idler according to different requirements, improve the adaptation range and applicability.

With this setting, it can be folded to reduce its overall length, facilitating transportation and carrying. After folding and unfolding, the clamping seat 26 is stuck on the support 25 to connect them. The limiting plate 33 is used to limit the maximum downward movement distance of the connecting plate 32. By setting the spring 42 to pull the lower arm 22, it is convenient to maintain the folded state during folding for transportation. At the same time, after the upper arm 21 and the lower arm 22 are unfolded, since the second fixing seat 43 is located on the side of the lower arm 22 away from the connecting plate 32, a force opposite to the hinged folding direction can be applied to the lower arm 22, facilitating the lower arm 22 to maintain a vertical state. When in use, the idler is placed in the groove 51, and the idler is supported by multiple elastic plates 52. The elastic plates 52 can be bent and deformed to increase the contact area with the idler, so as to support and fix the idler, improve the support and fixing effect, and reduce the situation of the idler falling off. By setting the elastic rubber strip 6 to contact the end of the idler, it can protect the idler and reduce the situation of the elastic plate 52 scratching the surface of the idler end. By setting the rubber pad 7, the friction with the surface of the belt conveyor channel steel can be increased, improving the fixing effect. Obviously, the above embodiments are only examples clearly described and not limitations on the implementation methods. For those of ordinary skill in the art, other different forms of changes or variations can be made based on the above description.
